Trigger enhancments, SD9 and 111G2
Hi All, 4/17/2016
I Have the SD9VE,And the Taurus PT 111 G2, among others
Like Most people, feel that the Triggers ( is or Are ).......Well, Needs improvement, and First off, I'm a Certified GM tech and Not a Gunsmith
But Have Been In the Automotive Business for over 40 years, I Have several
Firearms and Most will get the same Treatment That I perform on them , The SD9
Model suffers from Casting Slags Mostly in the striker system , as does the PT 111 G2, and most Strker fired Guns, if you remove the slide and work the striker by hand, you will feel the crunchiness of the striker, The trick is to remove the binding from the striker assembly. ( if your are the kind of Guy that will stab yourself with a screwdriver then This is not for you )
You will have to remove the striker cover off of the slide , Tools
Needed , Variable speed Dremel tool and Bit set,( Deluxe set) Small Jewelers set of screw drivers, , 3 punch set, small set, assorted, Magnifying Glass or Jewelers loop , Finishing sandpaper , 400,600,1000,(2000 if available) 1000 should do the
trick, 400 and 600 to clean surface's, Qtips and Your Choice of Gun cleaners the Taurus is a Little more involved to clean up,
For the SD9 Insert small Tip of Flat tipped screwdriver
to remove striker cover ,it will slide down , May have to Move Bushing forward, Just a little, Remove spring , watch out for small collets Don't lose
them , remove plastic slide bushing that The striker is in, Note you will see
two or black lines inside of Bushing assembly, Put off to side for later, we'll
get back to that , Take a look at the striker, On the end which rides into the
Bushing , Run Your finger tip along the edges , you will feel Machining or
stamping Marks, The trick to remove those edges , or really just clean them up,
so it does not binding or drag in the bushing , only remove enough so you do not feel the burrs anymore, It does not take much, polish striker pin assembly with 1000 only NOT THE POINTY END!!! leave it alone!!! put off to side, On both the Taurus and the SD, Lightly clean up the Plastic collets, Lightly! just enough to remove small casting burs, You can do this when Fully assembled, it easier,
Back to Plastic Bushing , If you have a Jewelers loop or Magnifying Glass you can look inside where the lines are that where the Crunchiness came from The striker was digging in to the plastic, Lightly clean up with 1000, also smooth out the Outside of Bushing too, The bushing should slide in and out , of upper slide, No binding, it should not be tight , if it is tight it will choke the striker , (My Taurus PT 111 G2 had this Problem But Worse! Now smooth as silk!!, That's another Forum But same Idea, Take some White Ultra fine Polishing compound (Turtle wax) and Mobil 1 very small amount just to keep the compound from drying out , Dab on a Small Artist Brush, Small amount coat inside of bore,and Plastic bushing , reassemble and Make sure it Moves freely, , Complete the assembly and
test You should Feel it Immediately, if done correctly , You can test just
working the striker inside the Upper slide, No more crunchiness, Your trigger system will feel completely different! and will Help you from Jerking or snatching the trigger , as from before the fight was to over power the trigger,This works for
ALL STRIKER fired hand Guns , Find out where the stamping Burrs are and remove them
Now the Taurus is a little more work, When you remove the Rear cap for the Striker, You Must bring the orange Bushing forward a little be careful not to overly scratch the bushing , once apart , you will notice that The Bushing does not slide out easy,( Make sure that the Trigger locking system is Fully Disengaged) this is where some of the binding is taking Place, The plastic Bushing is deformed for 3 reasons, The way its Manufactured, The Stamping process for the trigger locking system , and the Tightness of fitting in the slide bore, this needs to be really Cleaned out, this done in 2 parts, a dremel tool is required, a small cone shaped Bit , the Hole in the Bushing Needs to enlarged alittle and some what beveled, on the inside of the hole the trick is to clean up the Bruising Marks ,
When (the or A) Part is stamped, it creates(plastic Burs) and Because its a Hole it deforms the plastic, So when Pulling the striker it feels like a Stepping crunchiness , like a dead space, Clean out use the 1000 to clean inside , Roll finishing Paper like Barrel and slide through Bushing , clean up , Now for the Striker, Same Process as the SD9 Disassemble and find the Burs or slag marks , Clean up with 600, and then 1000, Note: SD9 had More problem areas on the striker, Taurus Not so much, more on the bushing side , NOW for the Slide, The plastic bushing fits too tight in Bore of Slide , this is where it chokes the Striker pin, we do this with a Dremel tool and the Small sanding Barrel, Dremel used with a speed control, clean out bore with sanding barrel and WD 40,( make sure that Trigger locking system is Fully disengaged ) clean out enough material to let the bushing slide freely you want the Bushing to be secure,Not sloppy or too loose but Slides fairly easy,because in the stock bore size,The bore changes the shape of the bushing, distorts it, You can Use Qtips and Bore cleaner to clean out any and all Mods,
Take the Bushing and slide into bore and test fit, also align with trigger locking system and make sure that there is more than enough clearance for lock to engage , if you are so inclined to use it, I do Not, Make sure that it does not sweep the bushing, if you engaged the lock,and try to use the trigger, you will create Burs, Lock is Metal, Bushing is Plastic, enough said, Used Polishing compound mix , lightly coat said parts, as with the SD9, reassemble and test fit, test Striker, results are Immediate, Your striker has no more resistance other than Spring energey, I’ve have done this on My SR9, SR9E, PT111G2, SD9ve, Any striker fired Fire arm will benefit from this Surface preparation in the slides, All are totally different Now, No More fighting the trigger, The trigger pulls are , SD9 5.9 , PT111 G2 5.7-6.0 DA 5.5 SA , SR9 & E 5.5 for both The SRs had Nice triggers,Now Like OMG!! Better!!!! IMO ,I did not want to spend thousands rounds of ammo to get an OK Trigger, I wanted a great trigger, and each Gun is different, The trigger linkage is pretty much stock on all guns,Except the SD9VE, needed a bit more, Have Gallaway full spring kit, except the striker spring ,Fits way too tight, did not want to sacrifice Striker spring energy, Apex trigger and Sear pivot mods,totally different gun Now,if this Helps anybody out there Great, God Bless
Thanks for Listening Boys and Girls,
